HPPD-IN-13

HPPD-IN-13 is a potent herbicide targeting HPPD, with an IC₅₀ value of 0.132 μM against EcHPPD. HPPD-IN-13 primarily forms bidentate coordination with the ferrous ion in the active site of HPPD, and competitively blocks HPPA metabolism via π-π stacking and multiple hydrogen bonds, ultimately leading to plant albinism and death. HPPD-IN-13 can be used in the research and development of novel bleaching herbicides.

In Vitro

HPPD-IN-13 (compound III-2) potently inhibits Echinochloa crus-galli HPPD with an IC₅₀ of 0.132 μM^[1].
HPPD-IN-13 binds stably to Arabidopsis thaliana HPPD through bidentate coordination with Co²⁺, π-π stacking interactions, and multiple hydrogen bonds, thereby contributing to its potent inhibitory activity^[1].
HPPD-IN-13 (active ingredient: 150 g/ha) inhibits the growth of Echinochloa crus-galli (99%-90%), Setaria viridis (89%-70%), Lolium perenne (89%-70%), Lolium multiflorum (99%-90%), and Abutilon theophrasti (99%-90%) in post-emergence herbicide assays^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
